Shortly after taking over as Diamondbacks general manager Kevin Towers made headlines for saying he’d be open to trading Justin Upton for the right package.

Two years later Upton remains in Arizona, but Ken Rosenthal of FOXSports.com reports that the Diamondbacks “are trying to trade” him following a disappointing season in which Upton saw his OPS drop 113 points compared to 2011.

Just last month owner Ken Kendrick said that the Diamondbacks were “highly unlikely” to trade Upton, but according to Rosenthal “the team is again engaged in active discussions.”

Rosenthal speculates that the Rangers could be a potential fit, mentioning shortstop Elvis Andrus by name. Last season Upton had the ability to block trades to the Yankees, Red Sox, Cubs, and Indians, but a source told Rosenthal that the list has since changed.

Upton is set to earn $9.75 million in 2013, $14.25 million in 2014, and $14.5 million in 2015. He’s still just 25 years old and one season removed from finishing fourth in the MVP balloting, but the Diamondbacks are pretty deep in outfielders thanks in part to the emergence of top prospect Adam Eaton and clearly have doubts about the former No. 1 overall pick’s ability to develop into a superstar.
